'To all whom it may concern:

Be it known that 1, ROBERT FIELDING, of 1088 Bury road, Breightmet, Bolton,-in the county of Lancaster, England, have invented a certain new and useful Improvement in Threading Devices for Loom-Shuttles, of which the following description, wherein reference is made to the accompanying sheet of drawings, is a specification.

It relates to improvements in or appertaining to loom shuttles of the kind which are provided with means for facilitating or effecting the threading thereof while the weaver holds the thread in -l1ishand,-so that the said thread is taken, caused to pass along the edge of a part mounted in the shuttle and under an extension thereof, these forming guides for said thread, other or additional parts being arranged to guide the thread to the outside of the shuttle and into the eye, and my said invention has for its object the production of an improved device of this type, the construction of which will enable same to be readily mounted in position so as to operate in conjunction with the well known guiding slit or groove formed in the wall of the shuttle to lead to the usual guide eye.

In the accompanying sheet of drawings which illustrates my invention :-Figure 1 is a plan of a shuttle showing the application thereto of my improved parts. Fig. 2 is a sectional side elevation, drawn to an enlarged scale, and shows certain of the parts illustrated by Fig. 1. Fig. 3 is a sectional end elevation on line A-B of parts shown by Fig. 2. Fig. 4: is a side elevation showing the eye of the shuttle. Fig. 5 illustrates a modified part hereinafter described. Fig. 6 is an end elevation of the part shown by Fig. 5.

In carrying my invention into effect according to one arrangement, I make use of a sheet metal device 2 of such a character as may be produced by the process of stamping and this device I mount in the end 3 of the shuttle 3, near where the eye or outlet l for the weft is situated, so that I may fix same in position by pins 5, which extend crosswise the shuttle. This piece 2 has its base part folded upon itself at 2 (see Fig. 3) to form a wing which will take into a groove in the base 3 of the shuttle while side parts 2 and 2 rest upon the base of the shuttle adjoining said groove intowhich' the wing 52 is fitted in order that the fixing pm 5 may be inserted crosswise through the walls ofthe shuttle to take through openings in the wing 2 there to secure same as desired.

Extending vertically on one side of the deviceQ, is the part 2 which reaches level -with the upper surface of the shuttle 3,

where it is bent laterally so that the bent part 2 may overhang the base part 2' beneath, while its extending end 2 reaches beyond the base part? and over a cavity 6 in the shuttle so that the thread passing from the shuttle peg 7 may be taken and conducted, while being held in the hand of the weaver, to pass into the slot 8 adjoining the overhanging piece 2 and forward to encircle the outer end 2 and descend thereunder, so as to finally be conducted into the slot or furrow 10 in the wall of the shuttle and passed forward down into the shuttle eye 4. By the part 2 extending level with the top of the shuttle protection is afiorded to the slot or furrow 10, so that same will not be readily damaged, while during the working of the shuttle in the loom the warp threads are not caught by said slot or furrow.

I may mount on the part 2 in proximity to the end of the spindle or peg 7 a piece of cloth or the like for the purpose of exercising a certain amount of tension on the thread.

Instead of the metal piece being of the shape shown by Figs. 1, 2, 3, I may have a wooden block of the shape shown by Figs. 5 and 6, in which case the pins 5 pass horizontally through openings 5 made in the base 5 of said block. The parts 2 and 2 are arranged somewhat of the shape hereinbefore described with reference to the sheet metal part 2.

Such being the nature and object of my said invention, what I claim is 1. In loom shuttles, a threading device having a base piece, a vertical side portion, an upper part lying flush with the upper surface of the loom shuttle and having an elongated nose the tip of which is depressed below said upper surface, this upper, part extending beyond the base and side parts, a groove formed in the shuttle for the reception of said threading device, pins for fixing said threading device in position, a slit in the Wall oftl'i-e; shuttle and a guide eye with Which said slit communicates.

2. The combination with a shnttle'havi'n'g' a lateral delivery-eye, an" i'ntercomlnunicating groove extending laterally from said eye to the upper surface of the shuttle, and

a threader-receiving chamber; of a th'reader 7 arranged in said chamber and comprising a head having an elohgatednpper surfacea portion of which is flush with the upper end ,of said groove but thenose of which is de- -pressed, abase portion secured in sald chamber,. and a -neclr portion connecting-said head andgba sesaid neck having a slanting thneadengag ng edge, arranged to. direct into. said groove'and eye a thread drawn across'said Asian, article 011 manufacture, a sheetmetal, threader for loom shuttles, said tl lreader having anelongatedhead, a base, and a conjoining neck, said head having a depressed nose, and-'s'aidneck having-a lateral bulge and a thread-engaging edge slanting in; a direction away from said nose and recessed. 7

l. As an article of manufacture, a sheetmetal' threader for loom shuttles, said threader comprising a base portion provided Witha pendent fold, a laterally bulged neck portion integral with said base portion and havingan elongated projecting upper end portion bent at approximately a right angle to form a head portion, the nose of said head portion beingdepressed below the ROBERT FIELDING.
